Specification of Letters Patent.

Patented May 7, 191%..

Application. filed April 21, 1917. Serial No. 163,545.

To all whom it may concern:

Be it known-that I, LOUIS MYERS, a citizen of the United States,residing at Detroit,

provide an improved means for'feeding and carrying the eyelets towardthe inaterial to be eyeleted.

It further has its object'to provide a means for receiving and carryingthe eyelets, which means will hold the eyelets thereon with a yieldingfrictional engagement.

It further has for its objectto provide a carrying means which willeasily enter the eyelets of varying sizes and carry them to the materialto which they are to be applied.

My invention constitutes an improvement upon the eyeleting machine shownand described in my Patent No. 1,174,948, granted March 7th, 1916.

The following is a description. of an embodiment of my invention,reference being 3 had to the which:

Figure 1 is a side view of a machine embodying my invention, part of theface plate being broken away;

Fig. 2 is an enlarged view of the lower front portion of the same;

F ig. 3 is a perspective view of the fastener-supporting springs, andportions of the tracks constituting a magazine;

Fig. 4 is a partial sectional view, showing the set and plunger and theguiding supports therefor;

Fig. 5 is a side elevation and bottom plan view of the radially yieldingplunger;

Fig. 6 is a detail view of the blank from which the plunger may be madeup by formaccompanying drawings, in

ing{ and swaging.

eferring moreparticularly to the drawings, which show my inventionembodied in an'eyeletingmachine, 1 is the frame of an eyeleting machinehaving a base 2; 3 is an anvil mounted on said base; 4 is a set forinsertin the eyelets when fed thereto; 5 is an actuatlng handle having acam 6 for actuating said set; 7 is a spring for retracting said set andhandle; 8 is a magazine for feeding the eyelets, composed of two tracks8' 8 9 9' are springs at the bottom of said magaend of said set.

zine for receiving eyelets from said magazine and holding them beneaththe lower end of said set 4, these springs being so proportioned that asthe set 4 descends they are forced apart so asto permit its lower end topass between and below them. ln the lower end of the set is a plunger 10having radially yielding prongs, which, when contracted, tends to expandand will expand so as to return to its normal condition. In its normalcondition it closely fits the hole in the lower In the constructionshown it is free to move upward in said set, and is normally held in theprojected positionby spring 11, Within said set, which bears upon theupper end of the plunger. This plunger is preferably made of sheet steelstamped in the form shown in Fig. 6, and then formed into cylindricalshape, and its lower ends slightly swaged inward to produce a shoulder12 and inwardly rounded surfaces 13 at its lower end. It is thenpreferably tem pered. This plunger, so constructed, can be compressedradially on all sides, the yielding prongs beingarranged concentricallyabout the axis of said set and will expand when so compressed.

The springs 9, 9, consist of side plates 14 screwed to the frame at 15and supporting front plates 16 which lie over the lower ends of thetracks 8, 8 Theupper ends of the plates 16 have inward extensions 17,which when the set 4: is withdrawn from between the plates 16, lie inthe path of the eyelets within the magazine 8 and when the set is indepressed position are separated so as to be out of the path of theeyelets. The space between the projection 17 and the set 1- when thepunch is depressed, is sufficient to receive one eyelet and one eyeletonly.

In the operation of the machine, as the set is being depressed, thelowermost eyelet in the magazine passes downward past the projections17, so as to fall by gravity to a position below the set and plunger asthe set rises and be there supported by the springs 9, 9. As the handleis depressed, the plunger 10 enters the eyelet, and in so doing isslightly compressed radially so as to make a frictional bindingengagement therewith.

'A further downward movement of the set 7 Copies of this patent may beobtained for on the bottom'side of the material to be fastened, theplunger 10 retreating within the set so as to permit this punching andcrimp ing action. On account of the radial COID- pression of theplunger, the eyelets are positively held and guided toward the materialto be eyeleted, and the operation is much more positive and certain thanif a solid unyielding plunger was used.

The lower end of the setis preferably beveled slightly at 18 so that theedgesof the. front plates 16 of the springs 9, 9, which contact with theset, can more easily enterbetween the end of the set and the rim of aneyelet carried by the plunger, so as to remove the eyelet on the upstroke of the plunger, as is desirable when the plunger is moved upwardbefore the eyelet has, been forced through the material to be eyeleted.As will be evident to those skilled in the art, myinvention permits ofvarious modifications without departing from. the spirit thereof, or thescope of the appended claims.

What I claimis: I

1. In an eyeletingmachine, the con1bination of a base and anvil carriedthereby, springs for supporting an eyelet above said anvil, aset abovesaid springs, and a normally, projecting sheet metal member carried bythe lowerend of said set, said projecting member beinghollow and havinga plurality of downwardly projecting yielding prongs for entering theeyelet.

2. Inan eyeleting machine, the combination of a base, an anvil carriedthereby, springs for supporting an eyelet above said anvil, a set abovesaid springs, and a normally projecting sheet metal member carried bythe lower end of said set, said projecting member being hollow andhaving a plurality of downwardly extending yielding prongs for enteringthe eyelet, said prongs being arranged concentrically about the axis ofsaid set, the lower ends of said prongs being turned inwardly toward oneanother.

3. In a fastening machine, the combination of a frame, an anvil carriedthereby, eyelet supporting springs located above said anvil, a sethaving at its lower end a radially yielding member having a plurality ofconcentrically arranged yielding prongs for en tering the eyelet, meansfor reciprocating said set, and tracks forming a magazine for feedingfasteners to said springs, said springs each having a face portionoverlying a portion of said tracks, and provided with a lateralprojection at its upper end and extending continuously from saidprojection to said plunger.

4. In an eyeleting device, the combination of a support, an anvilcarried thereby, a set, and a normally projecting sheet metal membercarried by said set, said projecting member being hollow and having aplurality of projecting yielding prongs for entering an eyelet andfrictionally holding the same.
